tools/power/x86/intel-speed-select: Update version

2020-01-20T09:39:32+00:00

As we added new set of mailbox commands, increment version. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Change the order for clos disable

2020-01-20T09:39:31+00:00

In turbo-freq or base-freq auto mode, for disable, first disable the feature and then disable clos. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Fix result display for turbo-freq auto mode

2020-01-20T09:39:31+00:00

The turbo-freq enable with auto mode, prints result for the last possible CPU, which is not correct when either CPU is not present or user wants command to be limited to a single die/package. For example, in the below command user wants to limit to die/package 0, but the "turbo-freq --auto" result is displayed using the other package. $ sudo intel-speed-select -c 0 turbo-freq enable -a Intel(R) Speed Select Technology package-0 die-0 cpu-0 turbo-freq enable:success package--1 die-0 cpu-31 turbo-freq --auto enable:success Since we do have to traverse all CPUs, don't display CPU info for "turbo-freq --auto", as we already displayed the result for turbo-freq enable with the CPU information. With the fix, the same command results in: $ sudo intel-speed-select -c 0 turbo-freq enable -a Intel(R) Speed Select Technology package-0 die-0 cpu-0 turbo-freq enable:success turbo-freq --auto enable:success Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Add support for core-power discovery

2020-01-20T09:39:31+00:00

It is possible that BIOS may not enable core-power feature. In this case this additional interface will allow to enable from this utility. Also the information dump, includes the current status of core-power. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Display TRL buckets for just base config level

2019-11-21T12:31:34+00:00

When only base config level is present, this tool is displaying TRL (Turbo-ratio-limits) by reading legacy MSR. In this case, also present core count for TRL by reading MSR 0x1AE. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Ignore missing config level

2019-11-21T12:27:32+00:00

It is possible that certain config levels are not available, even if the max level includes the level. There can be missing levels in some platforms. So ignore the level when called for information dump for all levels and fail if specifically ask for the missing level. Here the changes is to continue reading information about other levels even if we fail to get information for the current level. But use the "processed" flag to indicate the failure. When the "processed" flag is not set, don't dump information about that level. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Increment version

2019-11-07T17:00:25+00:00

Since the tool now adds support for another Intel SST implementation, increment version number. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Use core count for base-freq mask

2019-11-07T17:00:25+00:00

Some firmware implementation gives error when a command is sent get mask for core count 32-61. So use core count to decide. But there is no function to get core count. So introduce one function to get core count. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko

tools/power/x86/intel-speed-select: Support platform with limited Intel(R) Speed Select

2019-11-07T17:00:25+00:00

There are some platforms, where there limited support of Intel(R) SST features. Here perf-profile has only one base configuration and limited support of commands. But still has support for discovery of base-freq and turbo-freq features. So it is important to show minimum features to use base-freq and turbo-freq features. Here the change are: - When there is no support of CONFIG_TDP_GET_LEVELS_INFO, then instead of treating this as fatal error, treat this with number of config levels = 0, that means only base level 0 is present. - There is no support of mail box commands to get base frequencies or turbo frequencies. Here present base frequency by reading cpufreq base freq and turbo frequency by reading MSR 0x1AD. - Don't display any field, which has value == 0.

tools/power/x86/intel-speed-select: Use Frequency weight for CLOS

2019-11-07T17:00:25+00:00

Use different frequency weights for CLOS 0 and and CLOS1-3, to define relative priority for power budgeting. This will be used for --auto mode to enable base-freq and turbo-freq feature. Signed-off-by: Srinivas Pandruvada Signed-off-by: Andy Shevchenko
